Product details
Overview
TLC081AIP from Texas Instruments is a single-channel BiMOS operational amplifier optimized for wide-bandwidth, high-output-drive, single-supply operation. It delivers 10 MHz gain-bandwidth, ±57 mA output drive, 16 V/µs positive slew rate, and operates from 4.5 V to 16 V - enabling precision signal conditioning in automotive sensor interfaces and industrial analog front-ends.
For engineers reviewing the TLC081AIP datasheet, TLC081AIP pinout, TLC081AIP application, or TLC081AIP equivalent, key selection criteria include its rail-to-rail input capability (VICR = GND to VDD–2 V), ultralow 125 µA shutdown current per channel, and guaranteed 60 µV max input offset voltage at extended temperature (–40°C to 125°C).
Technical Context
The TLC081AIP employs a CMOS front-end with bipolar output stage, combining high input impedance (>1 GΩ) and low input noise (8.5 nV/√Hz) with robust ±55 mA sinking capability. Its architecture supports stable unity-gain operation with ≥32° phase margin into 50 pF loads.
Unlike legacy TL08x predecessors, it ensures ground-sensing common-mode input range and achieves >40 dB improvement in power supply rejection (130 dB typ). The device lacks shutdown control (SHDN pin not connected), distinguishing it from TLC080/TLC083 variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 10 MHz - enables accurate amplification of signals up to audio and ultrasonic frequencies without gain roll-off. |
| Output Drive | ±57 mA - drives heavy loads like 600 Ω audio lines or capacitive DAC buffers without external boost stages. |
| Slew Rate | +16 V/µs / –19 V/µs - supports fast transient response in pulse amplification and active filter applications. |
| Supply Range | 4.5 V to 16 V - compatible with 5 V, 12 V, and battery-powered systems including automotive 12 V nominal rails. |
| Input Offset Voltage | 60 µV max (A-grade) - reduces DC error in precision instrumentation and sensor signal chains requiring <1 mV total error. |
| Shutdown Current | Not applicable - TLC081AIP has no functional SHDN pin; pin 5 is NC per D/P package drawing. |
| Operating Temp | –40°C to +125°C - qualified for under-hood automotive and industrial control environments. |
Pinout & Package
Package: 8-pin PDIP (Plastic Dual In-line Package), 0.300-inch width, through-hole mounting. RoHS-compliant lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Null (NC) | No internal connection - unused pin; must be left floating or grounded per layout best practice. |
| 2 | Inverting Input (IN–) | Differential input node for feedback configuration; high-impedance CMOS input (1000 GΩ typ). |
| 3 | Non-inverting Input (IN+) | Reference input for follower or summing configurations; supports common-mode range to GND. |
| 4 | Ground (GND) | Analog reference return path; requires low-impedance connection to system ground plane. |
| 5 | No Connect (NC) | Corresponds to SHDN on TLC080 - unconnected in TLC081; must not be tied to any voltage. |
| 6 | Positive Supply (VDD) | Single-supply rail input; accepts 4.5 V to 16 V with 17 V absolute max rating. |
| 7 | Output (OUT) | Class-AB output stage capable of sourcing/sinking ±57 mA into resistive or moderate capacitive loads. |
| 8 | Null (NC) | No internal connection - unused pin; electrically isolated from die. |
Key Features
| Feature | Design Value |
|---|---|
| BiMOS Process Architecture | Combines CMOS input stage (low IB, low noise) with bipolar output (high drive, low Zo) - eliminates trade-off between precision and power delivery. |
| Rail-to-Rail Input Capability | VICR extends to GND - enables direct interfacing with sensors and ADCs operating at 0 V common-mode, eliminating level-shifting circuitry. |
| High Output Current | ±57 mA continuous - drives 600 Ω loads at full swing, supporting line-driver and actuator interface roles without external transistors. |
| Low Input Noise | 8.5 nV/√Hz at 1 kHz - preserves SNR in low-level signal paths such as thermocouple or strain gauge amplifiers. |
| Extended Temperature Grade | –40°C to +125°C operation - meets AEC-Q100 stress test requirements for automotive engine control modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2340UA | Single-supply rail-to-rail I/O, lower bandwidth (5.5 MHz), lower output drive (30 mA), higher quiescent current (800 µA). | Better for ultra-low-voltage (2.7 V) and precision I/O-critical apps; unsuitable for high-current line driving. | Select when rail-to-rail output swing is mandatory and load current <30 mA. |
| LM7332MA | Higher output drive (±80 mA), dual-channel, wider supply (2.7–36 V), but higher input offset (1.8 mV max) and noise (15 nV/√Hz). | Better for dual-channel, high-voltage, or high-current industrial motor control; less suitable for low-noise sensor amps. | Select when dual-channel integration or >16 V operation is required and offset/noise budget allows. |
Compared with OPA2340UA and LM7332MA, TLC081AIP uniquely balances 10 MHz bandwidth, ±57 mA drive, and 60 µV offset in a single-channel, extended-temp PDIP package - making it optimal for cost-sensitive, high-reliability automotive and industrial signal chains where discrete channel optimization matters.

FAQ
What is the maximum supply voltage for TLC081AIP?
The absolute maximum supply voltage for TLC081AIP is 17 V, with recommended operation from 4.5 V to 16 V. Exceeding 17 V risks permanent damage. At 16 V, the device maintains full performance including ±57 mA output drive and 10 MHz bandwidth, making it suitable for 12 V automotive systems with transient headroom.
Does TLC081AIP support rail-to-rail input?
Yes, TLC081AIP supports rail-to-rail input with a common-mode input voltage range (VICR) from GND to VDD–2 V. This allows direct interfacing with zero-referenced sensors and ADCs without level-shifting circuitry - a key advantage over older TL08x op-amps that cannot sense down to GND.
Is TLC081AIP pin-compatible with TLC080AIP?
No, TLC081AIP is not pin-compatible with TLC080AIP. While both use 8-pin PDIP packages, TLC080AIP has a functional SHDN pin at position 5, whereas TLC081AIP has NC at pin 5. Swapping them without board revision will disable shutdown functionality or cause undefined behavior due to incorrect pin mapping.
What is the input offset voltage specification for TLC081AIP?
TLC081AIP has a maximum input offset voltage of 60 µV at 25°C for the 'A' grade, with a typical value of 390 µV across the full –40°C to +125°C range. This tight DC precision enables high-accuracy applications like strain gauge amplification and medical instrumentation where sub-millivolt errors are unacceptable.
Can TLC081AIP drive capacitive loads?
TLC081AIP can drive up to 50 pF capacitive loads while maintaining ≥32° phase margin and stable unity-gain operation. For loads >50 pF, external isolation resistance (e.g., 10–50 Ω in series with output) is recommended to prevent peaking or oscillation - verified in TI's SLOS254F datasheet Figure 19.
